Time zone is now imported from the operating system, accounting for Day Light Savings time.

Overhead view option, so you can look up to the sky and the chart
simultaneously. In this representation, E and W are flipped and the chart is

Boat course plot, to easy printed chart orientation.
Star finder chart and table now print in the same sheet of paper, much more
convenient.
Using the Star Finder is easy:
1. Set your position (Lat/Lon)
2. Set the GMT date and time. If you opened the star finder by clicking the button in
the celestial navigation window, these values are automatically set.
3. Set the boat course (optional)
4. Click the Calculate button
You can also animate the sky, specifying time increments and calculation frequency.
This can produce very interesting animations, like how the sky changes from hour to
hour, day to day and year to year.
And it can also be set to show the current sky.
Chapter 3 - Chart Navigation to table of contents
The Navigator chart module is relatively new (started in version 2.5), but has received important additions in version 4.0.
It's now much more useful with the addition of raster chart capabilities.
Instead of supporting the existing electronic chart formats, I choose to provide a set of tools to allow the user to import
existing paper chart images into the program. This 'do-it yourself' approach gives the user maximum flexibility.
All Navigator files are in text format and their structures are easy to understand, to allow integration with other applications
and Internet file sharing. The table below enumerates the Navigator data file types.
